During the RubyConf 2024 hackday, while exploring some indexing behaviour using
irb
, there was some confusion because the index was referring to code that had been deleted.In this PR, I've added a check that raises on attempting to called
index_all
if it already contains entries.We could use a more technical approach such as adding a
reindex
method, or clearing the index each time when callingindex_all
. But since this is a relative rare usage, I think this protection is enough for the time being.
